I just got back from a week of primitive camping in Oklahoma. First time I got to use my new 125W panel from US Solar. It worked great! My biggest drain is the 85 qt. Whynter Fridge. The weather helped a lot - it was not too hot so the fridge didn't run a lot. I do have another 64 W panel that I didn't bring. When I get around to installing them permanently, I don't think I'll have any probs!
